The waves of Catholic immigrants to the USA did exactly what I propose. They founded their own parish communities with schools etc. They built beautiful churches and did great work for the Lord. There was nothing “vile, disgusting, abhorrent” in what they did. The Irish, Italians, Polish Catholics who built their own communities enriched the surrounding culture.
It was only
because they built up, to some extent, their own Christian culture, that they were able to benefit the larger culture. The communities did.
There needs to be a kind of compromise here, because the situation varies from place to place. Years ago I was thinking about joining the local Social Work Association chapter, with the idea that I could bring some of my values in networking with others. Then I read the results of a survey of their members, 97% endorsed abortion on demand. Had I joined that group, my dues and my time would have been wasted. But there are other secular groups where direction is still “up for grabs”. You can influence the “floating vote”.
Years ago, an argument might have been made to stay active in the local Democratic Party, where “I might influence things”. Today, that ship has sailed. You will influence nothing.
I do more good spending time in the K of C. The local council, of course, favors prolife, but I greatly expand what they do in that area.
In recent years American life has imitated trends in secular universities a decade earlier. So if you want to plan for the near future, find out how prolifers, or opponents of gay marriage, are treated in the big campuses now. As long as Newman centers are strictly limited to condemning Trump, conducting food drives and perhaps an ethnic dinner or two, they will be tolerated…for now.
That is what the climate on Main Street will be in a decade. We still have to try to influence Main St, but you may have to spend half your time in the monastery. The monastery will influence Main St, few individuals will be able to.
